SPECIFICATION forming part of Letters Patent No. 712,950, dated November 4, 1902.

Application tiled June 4, 1902. Serial No. 110,174. (No model.) l

To all whom it may con/cern,.- a coin-slot and raceway 6 and also with a Beit known that l, GALES P.V MOQRE, a citihorizontal slot 7 in one of its horizontal walls, zen of the United States, residing at St. Louis, (preferably the bottom wall,) suitable guides Missouri, have invented a certain new and 8 preferably extending from said`slot` '7, :A 55 5 useful Improvement in Telephone-Locks, of substantially vertical Slide-loarl ,extends which the following is a full, clear, and exact through said casing-slot 7 and .between said description, such as will enable others skilled guides and rests above and upon the suspenin the art towhich it appertains to make and sion-hook, said slide-bar being preferably use the same, reference being had to the acvprovided with a slot through which fa guide- 6o Io companying drawings, forming part of this pin extends.'

Referring now more particularly to the Normally the slide-bar rests uponthe susdrawings, 1 representsatelephone-box, which pension-hook and the locking-lever lies with can be of any suitable construction, and 2 inits coin-receiving arm in elevat'e'd'psition l`95 dicates the customarysuspension-hook for the under the coin-raceway and 'its hook engag usual telephone-receiverl. A box or casing4 ing the locking-surface ot the slide-bar and is secured to the wall or other suitable sup-"f intermediate the body of the said bar and port to extend atthe side ofthe said telephonethe overhan ging projection, all as shown' in box and over the said suspension-hook, Said Fig. 2. The Suspension-hook is thus locked Ioo 5o casing containing the hereinafter-described against movement, and as -this hook controls locking mechanism and being provided with the circuit through the telephone in a wellknown manner the telephone cannot be used. When a coin or token is deposited in the raceway, it falls upon the end of arm 14 and tilts the locking-lever until the hook 16 disengages thelocking-surface 11 and the upperendofarm 15 engages the overhanging projection, as shown in Fig.4,the parts being soproportioned and arranged that when the said lever is in this position its arm 14. still supports the coin or token, whereby the lever is maintained in the position last described. W'hen the receiver is lifted from the suspension-hook, the usual spring elevates said hook in a well-known manner, and as said hook rises it carries the slide bar with it, thus moving the said overhanging projection out of engagement with the locking-lever and permitting the coin to rock the said lever sufficiently to cause said coin to be deposited therefrom, as shown in Fig. 5. By the time that the coin has fallen from the coin-receiving arm 14 the slide-bar has been so elevated that its lock# ing-surface is above the point it occupies when engaged by the hook of the locking-lever, and therefore when the coin leaves the arm 14 the overbalanced locking-lever rocks toward the slide-bar and the hook comes to rest against the edge of the same, as illustrated in Fig. G. When the receiver is again hung upon the suspension-hook, said hook is depressed, and the support for the slide-bar being thus lowered said bar falls into normal locking position, the locking-lever hook falling into locking position as soon as the locking-surface of the bar falls below the end of said hook.

It will be noticed that the end of the arm -14 of the locking-lever normally lies under and near the lower end of the coin-raceway. By reason of this fact the guiding-pin 10 can be dispensed with, if so desired, and the bar will still be retained in the casing and prevented from unduly protruding therefrom even when the casing is not in position and the slide-bar is not supported upon the suspension-hook, for should the slide-bar fall its part over the locking-arm 15 engages said arm and the lever is merely rocked until its arm 14 engages the end of the coin-raceway.

The present mechanism is efficient and eX- tremely simple in its construction and operation. Pivoting of the bar which engages the suspension-hook is avoided, danger of rusting or breaking of the pivot is removed, and the bar acts directly upon the suspension -lever, merely sliding down upon the same by its own weight. The bar can be readily inserted through the casing-slot.

Manifestly the form of the locking-lever need not be that shown in Fig. 2 of the drawings. It can, for example, be made as illustrated in Fig. 7, the lever shown in said latter-mentioned figure having a substantially vertical locking-arm 15, which lies along and engages the edge of the slide-bar, and a substantially horizontal coin-receiving arm 14, the pivotal point 14:b of the lever being in said arm 14 a suitable distance from the arm 15, Furthermore, the slide-bar can, as shown in Fig. 7, protrude through a slot in the top of the casing and be provided with a hook 18, which engages over the suspension-hook. If necessary or desired, the slide-bar can be bent to bring the same in proper relation to the.

suspension-hook.

I am aware that many minor changes in the construction, arrangement, and combination of the several parts of my device can be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a telephone-lock or the like, a substantially vertically-slidable bar, a locking part thereon, a part upon said bar extending upwardly and laterally and then downwardly to produce an overhanging projection, and a locking-lever having its end intermediate said locking part and overhanging projection and cooperating with said locking part, said overhanging projection being in the path of movement of said lever to limit its movement vfrom locking position; substantially as described.

2. In a telephone-lock or the like, a substantiallyvertically-slidable bar,guides therefor, a coin-raceway, a lever intermediate said bar and raceway, a locking-surface upon said bar above the pivotal point of said lever and inclining downwardly and away from said 1ever, a portion of said bar extending upwardly and laterally and then downwardly to produce an overhanging projection, a locking-arm in said lever, a hook upon said locking-arm engaging said locking-surface and intermediate the body of said bar and said overhanging projection, said overhanging projection being in the path of movement of said lever to limit its movement from locking position, and a coin-receiving arm in said lever extending below said raceway, said locking-arm overbalancing said coin-receiving arm, the pivotal point of said lever being such that it can be rocked to deposit a coin without throwing said locking-arm backwardly beyond the center of gravity, and said bar having a surface engaged by said hook when the coin has been deposited and the bar elevated, said surface sliding along said hook as the bar descends; substantially as described.

In testimony whereof I hereunto aflix my signature, in the presence of two witnesses, this 2d day of June, 1902.
